This invention relates to a school desk.

The primary object is to provide a novel con-I struction permitting adjustment of the seat and of the desk, under control of a single spring means of novel form. I

A further object is to provide a construction wherein loosening of the wooden parts is avoided and the use of nuts, which constantly back out, is obviated.

The more specific objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawings illustrating an operative embodiment. i

In said drawings:--

Figure 1 is a view of the desk in side elevation,

Figure 2 is a view taken on the line 2- 2 of Figure 1, r

Figure 3 is an enlarged substantially central vertical sectional View taken through the pedes-' tals and associated parts,

Figure 4 is a cross sectional view line 4- of Figure 3,

Figure 5 is a cross sectional view line 5-'5 of Figure 3,

Figure 6 is a cross sectional view line 66 of Figure 3, and

Figure 7 is an elevation of the spring member alone.

Referring specifically to the drawings, 10 designates a base pedestal, the pedestal proper being shown at 11, and of hollow construction. Vertically slidable within the bore of the pedestal 11 is a desk-carrying pedestal or shank 12. The parts described are preferably square in cross section as shown.

The upper end portion of the shank 12 is reduced as at 13 and removably engaged by a socket taken on the taken on the portion 14 of a metallic bracket member 15, the

same supporting a desk 16. The bracket is adapted to be secured against accidental displacement by means of a screw 17 adapted to bind against the reduced portion 13. The side walls of the desk 16' are preferably made of metal while the remainder thereof is usually made of wood and screwed to the metal. In addition, a back as shown at 18 is adapted to be carried by the desk, such back usually being of wood. Thesaid back and parts of the desk additional to the sides 16 are preferably screwed to the sides 16, the use of bolts being avoided since the nuts thereof back off in practice and loosen the woodwork.

The tubular pedestal 11 has a series of notches on the side thereof and the shank 12 also has a series of notches on the side thereof as at 20. A

(01. 155 82) latchlspring is used as at same latch portions 22 and 23' extending at a right angle from opposite ends thereof and engageable respectively in the notches l9 and notches 20. The spring 21 is inthe form of a leaf spring and it has a central aperture asv at 24' which receives a-lug 25 on a sleeve 24. In addition the sleeve 25 is telescoped removably over the pedestal 11 and rotatably journaled thereon is a yoke or seat supporting member 26, the same resting on a shoulder 27 ofthe sleeve, and the seat being adapted for fastening in any rigid position desired through the tightening of a screw 28 against the sleeve. The seat supporting member or yoke 26 is preferably a casting and has arms 29. A seat is shown at 30 and on its under surface has ribs 31 which are bolted as at 32 to the arms 29. Since the bolts 32 are adjustable, they permit the seat to be adjusted and fastened in any desired positionand at any preferred angle.

3 5 therethrough to'accommodate an instrument or tool ,used in bending the spring to move the portions 22 and 23 out of their respective recesses so as to adjust the parts. Such action of the spring being permitted by clearance as at 36 formed in the bore of the sleeve. Since the 21, it maintains the latter in position on the lug 25 against accidental displacement.

Various changes may 7 they fall within the spirit and scope of the invention.

What I claim is:-

1. In a desk, 21. base pedestal, a desk member having a pedestal telescoped in the base pedestal, each of said pedestals having notches, a spring member engaging a selected notch in each of said pedestals, a sleeve slidably mounted on the base pedestal and secured to said spring, the spring thus supporting the deskpedestal and the sleeve, and a seat supported on said sleeve.

2. A device of the class described having a base pedestal, a desk pedestal telescoped therein, each of said pedestals having notches, a spring having lugs engaging a be resortedto provided selected notch in each of said pedestals, a sleeve slidably mounted on said base pedestal and secured to said spring,

each of said pedestals having notches, a spring having lugs engaging a notch in each of said pedestals, a sleeve surrounding said base pedestal and provided with means rigidly securing said spring to the sleeve, said sleeve having a shoulder, and a seat supporting means journaled on said sleeve and engaging saidshoulder, the desk pedestal and the sleeve thus being supported by the spring and -the-sleeve inz-turnpsupporting the seat. 7

4. A device of the class described comprising a hollow base pedestal, a desk pedestal telescoped therein, each of said pedestals having notches on the exterior thereof, a leaf spring having an 7 aperture and latch portions, one of said latch portions extending above the top of the base pedestal and engaging a selected'notch of the desk pedestal, the other latch portion engaging a selected notch of the base pedestal, a. sleeve surrounding the base pedestal, a lug on the sleeve interfitted with the aperture in said spring, said sleeve having cut away portions providing clearance for operation of the spring.

5. A device of the class described comprising a hollow base pedestal, a desk pedestal telescoped therein, each of said pedestals having notches on the exterior thereof, a. leaf spring having an aperture and latch portions, one of said latch portions extending above the top of the base pedestal and engaging a selected notch of the desk pedestal, the other latch engaging a selected notch of the base pedestal, a sleeve surrounding the base pedestal, a lug on the sleeve interfitted with the aperture in said spring, said sleeve having cutaway portions providing clearance for operation of the spring, and the latch portions having perforations to facilitate actuation of the spring.
